Dear VMD users
I'm using tcl script from "
http://www.ks.uiuc.edu/Training/Tutorials/science/10Ala-tutorial/tutorial-html/node6.html"
for sMD analysis.
The scripts were provided uploaded in the site and I'm using the same
example data.
While running the script "plot-force-extension.tcl" its shows error as
*"multiplot:
Data vector empty, ignoring plot and cant read "f(-1)": no such element in
array"*
This is the script i;m using for plotting grapg between force Vs distance.
set lcolor {green orange black pink brown purple yellow cyan blue red}
set plot2 [multiplot -plot]
foreach l [array names z] cl $lcolor {
set tmpz {}
set tmpf {}
set cnt [llength $z($l)]
for {set tmpi 0} {$tmpi < $cnt} {incr tmpi 10} {
lappend tmpz [lindex $z($l) $tmpi]
lappend tmpf [lindex $f($l) $tmpi]
}
$plot2 add $tmpz $tmpf -linecolor $cl
}
$plot2 replot
Kindly advice.
Many Thanks
Balaji
